Doing the bulk thing just sucks if you have a mild lactose problem and get sick easily from certain foods, I can't even stomach protein shakes without feeling bloated, constipated, and just sick all day.
I try to look at it this way, even though some of us are young and can probably handle a couple phases of throwing that food down your throat, is it really worth it feeling like crap day in and day out only for a few solid pounds of muscle? Im finding much more success recently from using zone guidelines/paleo guidelines and adjusting from there. Feel better, more energy, and weight gain can be adjusted. As a result, my own body weight is steady climbing back up.
I can't even manage to keep with mass gain like that half the time because life is so busy and im tired of feeling like shit all the time.
